Neural depth low framerate with TX2?

Software C++
1

I’ve just set up neural depth mode on my TX2 and got it running for the first time. The processing frame rate seems incredibly slow, even at VGA resolution. I have a loop running a simple grab() and printing out timestamps, and its reporting at most a 2Hz framerate. All of the other depth modes process at full camera framerate and resolution. Anybody else have luck getting neural depth to process more quickly?

Hi @pcdangio
the Jetson TX2 has lower capabilities with respect to the most recent Xavier NX/AGX and the Orin AGX.
The NEURAL depth mode is highly demanding and 2 FPS is indeed the maximum framerate achievable with the TX2.
Check that the jetson_clocks.sh script is running to be sure that you are exploiting the maximum available power of your board and run the ZED_DepthViewer tool in NEURAL depth mode to exclude eventual issues in your code, but do not expect higher FPS on the TX2.

Thanks so much for clarifying that limitation with the TX2! Guess I’ll be headed back to one of the other depth modes.

I know that Neural mode just came out, but FWIW, I think the community could benefit from a little more documentation on it. Especially system requirements :slight_smile:

Thanks again!

We are working on advanced versions of the Neural mode, working on less powerful devices… and on improving the documentation as well.
